If you have more than one automobile we strongly recommend that you purchase "stacking" insurance coverage. You can purchase stacking coverage for a nominal fee, and doing so will double the amount of no-fault coverage you can collect from your insurance in the event of an accident. This is especially beneficial for drivers who do not have medical insurance, because it provides affordable extra protection in the event of severe injury from a major crash. Stacking only applies to your no-fault coverage and does not apply to your liability, uninsured, or underinsured coverage.
